DS18 PRO-W10.4S 10" Water-Resistant Motorcycle Subwoofer 700W 4-Ohm SVC

The DS18 PRO-W10.4S is a full-size, water-resistant 10" subwoofer built for bikers who refuse to give up bass in the open air — the thump you can feel at 70+ mph, on a boat, or out on the trail. Made for motorcycles first, and ready for any build that needs a weatherproof sub.

Why we recommend it

Most water-resistant subs sacrifice loudness. The PRO-W10 doesn't — it uses a standard subwoofer basket, coil, and motor for real output, then makes the cone watertight with a durable lightweight plastic cone and rubber surround so water can't get into the working parts. The magnet and basket are coated to resist corrosion. It handles 350 watts RMS (700 watts peak) at 4 ohms and works well in both sealed and ported boxes.

Fitment & install notes

Sold individually (single speaker), single voice coil. 4-ohm — easy to match to most amps; also offered in a 2-ohm version to optimize your ohm load. Works in sealed or ported enclosures — supply appropriate power to get the full thump.
